There are certain types of flying bugs down here on the Gulf Coast that have shells a lot harder than The Motor Company's windshields. Consequently I was spending lots of money on Plastic polishes to do away with tiny scratches left by pesky little kamakazis. That hassle disappeared when I swapped the stock windshield on my '05 FLSTCI for a Memphis Shades stock replacement. Now all it takes to keep the shield bright and clear is a little dishwashing liquid and a 100% cotton cloth. BTW: Dennis Kirk's ad is incorrect: this shield fits perfectly well with stock H-D passing lamps.
